Congruence between selection on breeding values and farmers' selection criteria in sheep breeding under conventional nucleus breeding schemes
Designing breeding schemes suitable for smallholder livestock production systems in developing regions has hitherto been a challenge. The suggested schemes either do not address farmers' breeding goals (centralized ...
Reproductive performance and productivity of local and Dorper x local crossbred ewes under community-based management system, Ethiopia
This study evaluated the reproductive and productivity of local and Dorper crossbred ewes in a community-based management system. We analyzed data collected from 2013 to 2021, taking into account different factors such as ...
Relative resistance of Menz and Washera sheep breeds to artificial infection with Haemonchus contortus in the highlands of Ethiopia
The aim of this study was to evaluate the relative resistance of Menz and Washera sheep breeds to artificial infection with Haemonchus contortus. The challenge trial was conducted at the Debre Berhan Agricultural Research ...
Effect of strategic helminthosis control on mortality of communally grazed Menz lambs of smallholders in the cool central Ethiopian highlands
A 3-year longitudinal study was conducted to evaluate the effects of strategic anthelmintic dosing on communally grazed village sheep in Gera Keya district in the central highlands of Ethiopia. Ewes were stratified by ...
Reproductive Performances and Survival of Washera Sheep under Traditional Management Systems at Yilmanadensa and Quarit Districts of the Amhara National Regional State, Ethiopia
On-farm data were collected to evaluate reproductive performance and survival of Washera sheep raised under traditional smallholder production systems in the North-Western highlands of the Amhara National Regional State, ...
Growth performances of Washera sheep under smallholder management systems in Yilmanadensa and Quarit districts, Ethiopia
A study was conducted to evaluate growth performances of Washera sheep under smallholder production systems in the Yilmanadensa and Quarit districts of the Amhara National Regional State, Ethiopia. Data were collected and ...
Coat color alterations over the years and their association with growth performances in the Menz sheep central nucleus and community-based breeding programs
In the traditional Menz sheep breeding, communities select against black coat color and therefore its frequency is declining over time. We hypothesize that this exercise is causing the loss of an important gene pool. Data ...
Community-based sheep breeding programs generated substantial genetic gains and socioeconomic benefits
Community-based breeding programs (CBBPs) for small ruminants have been suggested as alternatives to centralised, government-controlled breeding schemes which have been implemented in many developing countries. An innovative ...
Morphological diversity of northeastern fat-tailed and northwestern thin-tailed indigenous sheep breeds of Ethiopia
Characterization of indigenous sheep breeds using morphological traits is essential for designing rational con servation and improvement strategies. This study was conducted to check the morphological diversity of three ...
Effect of genotype and environment on the productive and survivability traits of lambs under a community-based management system
The aim of this study was to evaluate the growth and survival of local and Dorper crossbred lambs managed under a community-based management system, using data collected between 2012 and 2021. The fixed effects considered ...
